BRUSH FORCLEANING BOTTLES.

SPECIFICATION forming part of Letters Patent No. 701,084, dated May 27, 1902- Application filed September 30, 1901. Serial No. 77,109. (No model.)

To all whom, it may concern.-

Be it known that I, ANDERS ANDERSEN PINDSTOFTE, manufacturer, of Vesterbrogade 66, Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in Brushes for Cleaning Bottles, of which the following is a specification.

This invention relates to a special improvement of the commonly-used revolving brushes for cleaning the inner surface of bottles. As the revolving brush-spindle always must be considerably thinner than the inner circumference of the neck of the bottle, the fastening of the brush material has hitherto offered great difficulties. The problem which had to be solved consisted in constructing a brush which can pass through the neck of the bottle without any ado and on which the brush material is fastened in such a manner that the whole inner surface of the bottle is washed by the brush and that the brush material I have solved this problem by arranging a number of strips of caoutchouc or other similar materials on the spindle without applying any fastenings and in such a position that worn-out strips may be removed and new strips inserted without special means being applied, the strips at the same time being kept firmly in their place while the brush is revolving.

In the accompanying drawing, illustrating the preferred embodiment of my invention, the figure is an elevation of my brush, partly in section, the upper part showing the strips when the brush is revolving and the lower portion their position when the brush is at rest.

The new improvement consists in the holes in the spindle I) being bored obliquely and arranged in such a manner that the up point of each hole is on a level with the down point of the next hole above, and so on. This will be seen from the drawing, in which the line A A is laid through the up point of one of the holes and the down point of the next hole above. The strips are passed loosely through the holes, and thus take up the oblique position as shown in the lower part of the drawing.. When the brush is revolving speedily, the strips, however, will take up the position shown in the upper part of the drawing and will thus be secured to the spindle.

From the upper part of the drawing it will further be seen that the strips 01, during the revolving movement of the brush take up a position in which the ends of the strips on one side of the spindle are covering the surface lying between the ends of the strips on the opposite side of the spindle. Thus no part of the inner surface of the bottle is left unwashed. I

The end of the spindle is formed as a tube, in the walls of which the perforations are made. The strips are passed out through the holes and collected ina sort of bundle through the opening of the tube, around which they will form a bundle of rays while the spindle is revolving. The latter strips are intended to wash the bottom and the lower part of the bottle.

Having now particularly described and ascertained the nature of my said invention, I declare that what I claim is- Improvement in brushes for cleaning bottles formed of strips of caoutchouc or other suitable material inserted in a spindle, characterized thereby, that the strips are inserted loosely in holes, which are bored obliquely throughthe spindle and arranged in such a manner that the upper point of each hole is in level with the lowest point of the next hole above, and so on.

'In witness whereof I have hereunto set my hand in presence of two witnesses.
